Rated 5 out of 5 by EliteCut from Don't Overlook the BR450I'm in the lawn business, and we do about 15 yards a day. When it comes to tool selection, we test them out first in the field before buying. Power, price, size, weight and reliability are some factors we considered before making the purchase. My local dealer was nice enough to let us test out various Stihl commercial blowers at our jobs and our final decision was between the BR700 and BR450. We ultimately decided to add a couple of the BR450s blowers and returned the BR700 for the following reasons:1. Our backpack blowers are locked on the trailer rack, but we sometimes need to place them in the back of the truck bed which has a hard cover. The BR450 was smaller in size so it fit with the lid closed. The BR700 did not fit with the covers closed.2. The BR450 felt lighter and was better on fuel after hours of use. 3. The BR450 has more than enough power we need for our heavy duty job. It was not much more money for the BR700, but there was no reason to pay for extra power that we don't need. 4. The BR450 is two stroke as oppose to the four mix BR700. We service all our mowers and equipment. In short term, there is no difference on maintance between the two. In the long run, we noticed the two stroke is easier to work on and more reliable.In conclusion, while the BR700 is a beast, with a lot of CFMs, and the most powerful Stihl blower money can buy, the BR450 has way more than enough power to get the job done. Remember, you get paid the same regardless which blower you choose. And don't forget, the BR450 is another top of the line Stihl commercial blower just like the BR700!

Rated 5 out of 5 by Codeash from Outstanding Blower!I was looking for a new blower just to keep up with the leaves and pine needles in the drive and beds. I have a landscape company doing the yard but there are times the leaves and needles start dropping and could use touch up before they get back the next week. I was going for the BR 200, I liked the light weight but the power was not as strong as I had hoped for. I purchased the BR 450 and WOW ! this is truly the blower to get... they should just sell this one blower. I live on one acre and I cleaned out the flower beds by blowing only where the pine needles and leaves had been dropping and now have a yard full of leaves and needles to pickup that are about 2 feet deep and 20 feet long. Very strong blower, easy to start, well balanced, no vibration, and the adjustable nozzle and throttle are great .... what are you waiting for .. bite the bullet and buy one, you will like it for sure!

Rated 5 out of 5 by Joel1 from Love it.This blower is awesome. I'm a home owner and has had plenty is elec blowers. The 450 is a lot of money to me but I've always wanted a backpack blower. So after 63 years on the planet I finally said it was time. Man when I got home and used it for the first time it was way cool. My yard never looked so good. Well worth the investment! I've used a lot of equipment in my lifetime but to own something like this was wasn't happening. I'm glad I bought one. It's probably more than I need but it's nice to have the extra power. Two pulls on full choke, two pulls on half choke and it's purring! Good fule mileage.

Rated 5 out of 5 by Rocketman from reliable and powerfulI use my new BR 450 blower to remove pine cones, leaves, hickory shells, small branches, etc.. Does an excellent job.Having several Stihl products over the years, I currently have and use:. 2 chainsaws, a pole saw, a blower, and a weed eater. Reliability and durability of all products has always been great. Living on and personally maintaining 11 acres that I keep looking like a park keeps me and by Stihl products busy. Wouldn't buy anything else.
